When we take up the relationship of social anthropology with other social sciences, the immediate question which confronts us is what we mean by social anthropology in terms of its tradition. In Britain, social anthropology means ethnology or sociology; in the US it refers to culture, and in France and other countries it means structuralism.
The point is that all the branches of anthropology have varying meanings and traditions in different countries. Such a situation cautions us from relating _social anthropology with other social sciences keeping in view the specific meaning given by different traditions to social anthropology.
Yet another explanation is necessary. There are two kinds of relationships in anthropology. One is of sister type. For example, anthropology has some important branches, such as social anthropology, cultural anthropology, ethnology, pre-history, linguistics, and physical anthropology.
The relationship among these branches is sisterly or collateral. There is another level, for instance, that with economics, politics, history and psychology.
